Hello there, Byron. To provide the most accurate guidance, please specify if you are referring to a QuickBooks Debit Card, a bank debit card, or another type of debit card. Each type has different methods or support routes for locking the card to ensure financial security.
In the meantime, if you'd like to lock your debit card for a QuickBooks subscription, please know that this feature is currently unavailable. However, you can always change them anytime. For detailed guidance, please refer to this article: Manage billing, payment, and subscription info in QuickBooks Online.
On the other hand, if you want to lock your QuickBooks Checking debit card, you'll have to zero out the balance first by spending your remaining balance or transferring it to your external bank account.
If your balance is already at zero, you can call our QuickBooks checking team using the number on the back of your debit card. Our team is here to assist you with everything you need.
Additionally, you can visit our QuickBooks Checking FAQ to get answers to frequently asked questions about QuickBooks Checking.
You can also check out this article to learn how to deposit customer payments into your bank account in minutes: Get instant deposits in QuickBooks Online.
I'll be on the lookout for any other concerns you might have, Byron. Your financial security is a top priority, and we're here to lend a hand whenever you need it. Take care, and don’t hesitate to reach out whenever you like.
